COOKING-stove.

SPECIFICATION forming part of Letters Patent No..673,*701, dated May '7, 1901.

Application filed October l2. 1900- Serial No. 32,874. (No'model.)

To @ZZ whom. it 11i/ay concern:

Be it known that I, DAVID CLINE, a citizen of the United States, residing at Watsontown, in the 'county of Northumberland and State of Pennsylvania, have invented new and useful Improvements in Cooking-Stoves, of which the following is a specification.

My invention relates to improvements in cooking-stoves, and pertains more particularly to a combined cooking-stove and a hotwater generator.

One object of my invention is to provide a stove of the class described in which the tank for generating hot water has a great-er hea-ting-surface and so arranged that the draft from the fire can be either above or below the tank or both below and above Another object of my invention is to pro' vide means for protecting the generatingtank from the full force of the heat when the stove is simply used forv cooking, as would be the case in summer-time.

A still further object of my invention is to provide a protector which is easily and quickly placed in the stove without in the least affecting the cooking qualities of the stove.

Referring now to the drawings, Figure 1 is a top plan view, partly broken away, showing the arrangement of the lids and the protecting-plates. Fig. 2is a longitudinal sectional view on the line 1 l, Fig. l. Fig. 3is a longitudinal 'sectional View on the line 2 2, Fig. 1. Fig. 4 is a transverse sectional View on the line 3 3, Fig. l. Fig. 5 is a transverse sectional view on the line 4 4, Fig. 1. Fig. 6 is a side View of my improved stove. Fig. 7 is a longitudinal sectional view taken on the line 5 5, Fig. 6. Fig..8 is a longitudinal sectional view taken on the line 6 6, Fig. 6.

Referring now to the drawings, A represents the outer casing of the stove, which is of the ordinary shape. The said casing has a removable top B, which is provided with a and the upwardly-extending grate'.

ing a transverse opening c, which will be hereinafter more fully described. The said is a transverse vertical partition a, which forms the end of the oven.l A second parti-v tion c is arranged transverse the Casin(r and extending forward from the partition to the front of the casing is a plate d, which forms the bottom of the lire-box C. Resting on said plate is a grate-frame d', which carries a, series of independently-rocking grates e Resting on the transverse partitions a and c is a plate f, which' forms the top of the oven C. The said plate f is provided on either side with longitudinally-extending inclined portions g, which are provided with horizontal portions g', which res-t upon the strips f', carried by the side of the casing. The strips f not only serve as supports for the top of the oven, but also form a comparatively air-tight joint. The horizontal portions g' of the plate fserve as supports for the generating-tank and also for the purpose of keeping the tank off the plate f, forming a space or iiue between the top of the oven and the bottom of the boiler. Adamper D is pivoted between the forward ends of the inclined portions g, adjacent the fire-box, whereby the said space or flue c may be closed. The pivoted connection at one side of said damper extends ont through the oven C and has an operating-handle D on the outside of the stove, whereby the damper can be opened or closed.

Below the damper D in the platef is an opening h, which registers with an air passage-way h', which extends through the oven C and is in communication with the space 72, below the oven, whereby a hot-air passage or current is conducted beneath the oven C and out through the transverse opening c.

The rear end of the fire-box has a series of openings o, which communicate at all'times with the air passage-way h', thereby heating the space below the oven. The plate d does not extend all the way across the stove, but leaves a space on either side thereof.

The generating-tank has a flat portion j, which rests on the horizontal portion g of the top of the oven, thus leaving an air-space IOO therebelow. The said tank is provided with forwardly-extendingportions H,having downwardly extending portions H', which are adapted to enter the spaces on either side of the grates and which extend down to I(he horizontal portion in the bottom of the casing and rest thereon. It will be readily seen that the tank nearly completely surrounds the firebox, or, in other words, forms three sides of the tire-box. Thus a greater heating-surface is obtained than in the' type of stove in ordinary use. The rear dat portion of the tank does not extend to the end ot' the casing, but leaves a space or opening equal to the distance between the end of the oven and the casing. By this construction it will be readily seen that a liuc c is formed there to allow the hot air or smoke which passes under the oven or between the oven and the tank to pass out through the opening in the top ofthe stove, which is connected with the ordinary stovepipe.

The top of the flat portion of the tank carries a damper K, which is adapted to close the opening left at the end of the tank. The said damper is pivoted, as shown at 7c, one of the pivots extending through the casing, as shown at 7c', and having an operating-handle Z attached .thereto whereby the damper is operated.

The tank on either side is provided with outwardly-extending pipes passing through the casing and connected to a heating device of any character.

When the stove is not being used for heatofthe tank. The inner faces of said extending portions are provided with downwardlythe downwardlyextending portions of the tank. When this protector is used, it will readily be seen that instead of the tank forming the fire-box the said protecting-plate covers all portions of the tank coming in contact with the fire-box. The flat portion M of the protecting plate has a central opening or channel P, forming a smoke-conduit. The said channel is directly below the row of plates carried by the top of the stove, whereby the stove-lids carried thereby are in direct communication with the fire.

The box-like portion M is provided at each side with openings which register with openings in the side of the casing. Sliding dampers 'n are arranged on the outside of the casing, having openings registering with the opening in the casing. It will be clearly seen that the box-like portion of the protectingplate can be cooled as desired without aecting the heat within the central channel P. The said protecting-plate is not as long as the etat/o1l tank, so that the damper K can be swung up to close the outer endV of the channel P. The said channel is also provided at its inner ends with a pivot-ed damper S, whereby the end of the channel adjacent the [ire-box can be closed.

One side of the stove is provided with doors T, which open into the oven, and the opposite side is provided with a sliding dam per U, which has openings registering with openings o in the side of Ithe oven. The forward end of the stove is provided with a damper t, opening into the lower air-passage beneath the oven.

When my device is not used for heating purposes, the protecting-plate is inserted, and it will be readily seen that all portions of the tank exposed directly to the heat are covered by the said protecting-plate. If it is d esired simply to cook on the top of the stove, the damper D is closed, the damperv S is opened, and the damper K swung upward, so that the end of the channel beneath the Alids is partially closed at its near end and the heat confined therein to a certain extent. The operation would be the same if the protecting-plate vwere not used, except that the heat would not be confined directly below the lids. When it is desired to bake, the damper S is closed, `the damper D opened, and the damper K swung down to close the flue c, whereby the heat is confined between the boiler and the top of the oven, in the space below, and at the end thereof.

When the device is used for heating purposes, the protector is removed, and the tank then forms the re-box, the whole top of the tank being exposed directly to the heat. The tank can be entirely surrounded by heat by simply opening the damper D, which allows the heat to pass beneath, around the end, and through the passage c. Y

What I claim, and desire to secure by Letters Patent, isextending plates O of a size equal to that of 1.
